It's easy to sightsee on your own on Rarotonga. The “island bus” will take you anywhere along the road that circles the island, including two top beaches. Buses leave from the Cook’s Corner bus station in Avarua: the Clockwise on the hour and the Anticlockwise (counterclockwise) on the half hour. It takes about 16 minutes to reach Muri Beach on the clockwise route, and 19 minutes to get to Titikaveka Beach. Hop on the Anticlockwise bus to return to Avarua—or, if you have the time, complete the whole loop to see more of this gorgeous island.
